Around October the dashboard displayed a message saying the key fob battery was low and need changing. I did this but was surprised as the vehicle was only 18 months old then. Last week the same thing happened so I changed it again. Now it's happened again today......is there some sort of reset required after a battery change? Other than the message, the fob is working perfectly well.

Any advice most welcome

What brand batteries are you using?

Duracell 2032

Several threads on this issue if you have a search around, such as:

My originals lasted 3 years, replacement Duracells about 20 months, though one failed again almost immediately (dud or fake, I wonder?)

There are reports of counterfeit Duracells getting into legitimate supply chains. 

Other points (though these would normally stop the fob working immediately):

- ensure the battery is the correct way up and free of fingermarks,  etc

- Duracells have a warning sticker which needs to be peeled off and can leave residue which needs to be thoroughly cleaned off.

BTW - is your other fob still ok?

 

 

 

 

Use either Energizer or Panasonic CR2032.

For about a year or more there have been many issues with counterfeit Duracell batteries even when bought from reputable supplies.

A brand new battery should measure 3.30volt and will start to give low battery warnings when it falls below 2.99volt

If after fitting a known good (tested with a meter) battery your car still displays the message that the keyfob battery is low, then you need to do the reset to clear the warning.

Many thanks......how do you reset?

Personally, I like a long hot soak in the bath, surrounded by candles, with some Barry Manilow playing in the background...
